In bbuchsbaum/neuroim2: Data Structures for Brain Imaging Data

Create Binary Reader Object

Description

Create a new instance of the BinaryReader class for reading bulk binary data.

Usage

BinaryReader(
  input,
  byte_offset,
  data_type,
  bytes_per_element,
  endian = .Platform$endian,
  signed = TRUE
)

Arguments

input	Character string (file name) or connection object to read from
byte_offset	Integer specifying bytes to skip at start of input
data_type	Character string specifying R data type ('integer', 'double', etc.)
bytes_per_element	Integer specifying bytes per data element (e.g., 4 or 8)
endian	Character string specifying endianness ('big' or 'little', default: platform-specific)
signed	Logical indicating if data type is signed (default: TRUE)

Value

An object of class BinaryReader

Examples

# Create a temporary binary file
tmp <- tempfile()
writeBin(rnorm(100), tmp, size = 8)


# Read from existing connection with offset
con <- file(tmp, "rb")
reader <- BinaryReader(con, byte_offset=0,
                      data_type = "DOUBLE", bytes_per_element = 8L)
close(reader)

# Clean up
unlink(tmp)
